Galvanically isolated switch designed to expand the capabilities of the Shelly Pro 3EM device. Easily control electrical devices with greater flexibility and control over your consumption.
Only compatible with Shelly Pro 3EM and Pro 3EM 3CT63
Key Features:
Contactor Control: Provides a dry contact relay (up to 2A) to enable the Shelly Pro 3EM to trigger heavy-duty contactors, controlling high-power loads.
PV System Balancing: Allows for intelligent energy redirection; when solar generation is high, the device can turn on water heaters or EV chargers to maximize self-consumption.
Weather-Driven Automation: Enables scripts that act on weather forecasts, such as shutting down heating if a sunny day is predicted, saving energy.
Galvanic Isolation: Ensures electrical safety and prevents interference between the high-voltage load and the Shelly Pro 3EM device.
Easy Integration: Specifically designed to attach directly to the Shelly Pro 3EM, powered via 3.3 VDC/12 VDC directly from the base unit.
Compact Design: Fits onto a DIN rail, making it ideal for integration into standard breaker boxes.
